Almost all of the main terms for both the mean and the turbulent kinetic energy equations have been evaluated with the experimental data in the three-dimensional jet issuing from the cruciform nozzle. In addition, the measurement of secondary flow vectors has been made in order to describe the cause closely related to the features of the present jet. It is clarified from the estimation of each term for the mean kinetic energy equation that on the y' axis the work term w'_<m1> is very different in tendency from that of the two-dimensional jet. For this reason, the developing process of the present energy equation that the magnitude of all mean terms varies remarkable depending on the local have a peak in magnitude associated with the secondary current.
